LIQUID CRYSTAL DISPLAY WITH INTEGRATED SWITCHES FOR DC RESTORE OF AC COUPLING CAPACITOR

摘要

An AC-coupled display driver circuit include one or more DC-restore switches that are integrated within a liquid crystal display, A liquid crystal display system includes a coupling capacitor coupled at one end to asystem input video signal, the coupling capacitor providing a display input video signal having a DC level offset. A liquid crystal display device coupled to another end of the coupling capacitor receives the first display input video signal at a video input for driving the display device. A switch integrated within the display device provides DC restore to the coupling capacitor.
